Part A
Define 6LoWPAN.
Answer
6LoWPAN stands for IPv6 over Low-Power Wireless Personal Area Networks. It is an adaptation layer that enables the transmission of IPv6 packets over resource-constrained wireless networks, such as IEEE 802.15.4, by providing header compression and fragmentation mechanisms necessary to fit IPv6 packets into small link-layer frames.
Explain about transport layer.
Answer
The transport layer in the IoT architecture is responsible for the end-to-end delivery of data packets between devices and cloud platforms or gateways. It ensures reliable, ordered, and error-checked delivery of data streams across the network.
Key functions and protocols include:
- Reliability and Flow Control: Protocols like TCP (Transmission Control Protocol) provide connection-oriented communication, ensuring that data packets are received in the correct order and without loss through acknowledgment mechanisms.
- Efficiency and Low Latency: Protocols like UDP (User Datagram Protocol) are frequently used in IoT for real-time applications where speed is prioritized over guaranteed delivery, as they have lower overhead.
- Congestion Control: The layer manages network traffic to prevent packet loss during high-volume data transmission from multiple IoT sensors, maintaining overall system stability.
